The Ultraloq U-Bolt Pro combines eight entry methods-including a 360° fingerprint sensor-with built-in 2.4 GHz Wi-Fi and an IP65-rated housing for robust outdoor use.

Professional reviewers commend the Ultraloq U-Bolt Pro for its unmatched versatility, noting the eight entry methods, reliable 360° fingerprint sensor, and the convenience of built-in WiFi that removes the need for a hub. The lock's ANSI Grade 1 certification, IP65 rating, and integrated door sensor are highlighted as strong security and usability features. Criticisms focus on the WiFi's 2.4 GHz limitation, the relatively short battery life of the WiFi model, and occasional finicky setup, as well as the bulkier form factor that may not suit every door.
Everyday users appreciate the easy installation, rapid fingerprint unlocking, and the ability to grant remote access to guests via eKeys. The door sensor's auto-lock function and the long-lasting AA batteries receive frequent praise. Common complaints revolve around fingerprint failures in wet or cold conditions, occasional app glitches during WiFi pairing, alignment challenges with the door sensor on warped doors, and a louder click compared with other smart locks.
